2. The rate of change of the velocity as a function of time while the cart was rolling freely is constant. The significance of the negative slope is that the cart was moving in a negative (downward) direction.
3. The more the track is elevated the steeper the slope becomes.
4. The quantity at t=0 for the linear fit would be the intial velocity for the car is it was not pushed and moved freely the entire time.
v=vo+at
